Question

使用以下命令编译应用程序后：

javac -cp bcprov-jdk15on-162.jar EncryptionTool.java

当我尝试使用它运行时，哪个可以成功运行

java EncryptionTool

我明白了

相关代码：

import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
import java.security.Security;
import java.util.Base64;


public class EncryptionTool
{
    public static void main(String[] args)
    {
        Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
        String result = Encrypt("password");
        System.out.println(result);
    }
}

这几乎都是普通的Java，没有任何凹痕或蚀。只需使用javac进行编译，并使用java运行+记事本。

顺便说一下，加密是一种方法，而不是大写字母所暗示的类。
